Hi, I saw the upgrade requires a sd flash to do so, but strange requiring us to buy one? Formatting a SD shouldn't be terribly difficult to do, particularly under linux that I use for everything, so is it possible to provide an image to write to a SD ourselves?
It's rather annoying after spending $600 on this unit that seems not to work more often and doing so, we should have to order some magical formatted SD to do this, just in hopes maybe you have fixed some of the other instabilities in the OS present in prior releases. These really should be sent as a courtesy to current customers, as these were sold documented that these "would receive" 8.1, not that it "would come with a paid update a year later".
Or let us capable of DIY flash ourselves.
